The chemical structure is unchanged.
Melting is not a chemical change because the chemical formula of water remain unchanged.
chemical change
the chemical composition does not change.
Physical Change
The melting of ice is a physical not, not a chemical change. You can tell this because the chemical composition of ice and water are exactly the same, i.e. they are both H2O. Only the physical property has changed since one is a solid and one is a liquid.
Physical because none of its chemical property's are not changed. Its still ice, just melted

physical change
no because the change goes back again on the cooling process
It is a physical change.
It is a physical change.
when the temperature around the ice gets warmer, it melts it. When you put ice in water, the water is actually warmer than ice (hence the ice to cool it off) and the ice naturally melts because it is submerged in the lower temperature.
